• Driving the development and sustainment of multi-tier offensive cyber applications and systems, ensuring mission readiness and resilience.
• Applying expertise in distributed systems (microservices, APIs, queues, SQL/NoSQL databases) to scale mission-critical operations.
• Writing, debugging, and optimizing code across multiple languages and frameworks, including Python, Java, C#, JavaScript, TypeScript, HTML, and CSS.
• Leveraging Django, Node.js, and other frameworks to deliver robust, full-stack solutions.
• Leading and mentoring junior developers, setting technical direction, and managing daily team tasks.
• Integrating cybersecurity solutions (IDS, EDR, EPP, AV) and operating system internals knowledge (Windows, Linux, MacOS, iOS, Android) into full-stack builds.
• Utilizing collaboration and version control platforms (Git, GitHub/GitLab, Jira, Confluence) to drive efficient workflows.

What you need to succeed:

• Must be able to obtain a TS/SCI clearance
• Bachelor's degree in Computer Science, Electrical Engineering, Information Systems, Cybersecurity, or equivalent professional experience.
• 8+ years professional experience writing and debugging software in modern programming languages.
• 8+ years in full-stack frameworks/environments (Django, Node.js, etc.).
• 6+ years building and maintaining full-stack, multi-tier offensive cyber applications.
• 4+ years in distributed systems (microservices, APIs, SQL/NoSQL databases, queues).
• 4+ years working with version control and collaboration tools.
• 4+ years applying modern cybersecurity solutions to production systems.
• 2+ years of operating system internals experience (Windows, Linux, MacOS, iOS, Android).
